(let me know if I am missing something.) Thanks a lot for all of your contribution! (and also Kconfiglib, I used in U-Boot)

menu_end_entry() is empty and completely unused as far as I can tell: $ git log -G menu_end_entry --oneline a02f057 [PATCH] kconfig: improve error handling in the parser 1da177e Linux-2.6.12-rc2 Last one is the initial Git commit, where menu_end_entry() is empty as well. I couldn't find anything that redefined it on Google either. It might be a debugging helper for setting a breakpoint after each config, menuconfig, and comment is parsed. IMO it hurts more than it helps in that case by making the parsing code look more complicated at a glance than it really is, and I suspect it doesn't get used much. Tested by running the Kconfiglib test suite, which indirectly verifies that the .config files generated by the C implementation for each defconfig file in the kernel stays the same.
